Robotics Science and Systems (RSS) 2011 will bring together researchers working on algorithmic and mathematical foundations of robotics, robotics applications, and analysis of robotic systems. The conference is single-track, and the final program will be the result of a highly selective review process, to give attendees an opportunity to see the best research in all areas of robotics. The program will include invited talks as well as oral and poster presentations of refereed papers. The main conference will be preceded by one and a half days of workshops and tutorials. Every effort is being made to keep conference expenses affordable, particularly for student attendees. All papers presented at the conference will be made freely available for download on the Internet.
